ELECTRIC CONDUCTING-CABLE.

SPECIFICATION forming part of Letters Patent No. 686,832, dated November19, 1901.

Application iiled September 21, 1900. Serial No. 30,712. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, JQHNDPEACHEY, a citizen of the United States,residing at Newark, in the county of Essex and State of New .Iersey,have invented certain new and useful Improvements in ElectricConducting-Cables; and I do hereby declare the following to be a full,clear, and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which forni a part of this specification.

The objects of this invention are to facilitate the work of making wireconnections in connection with telephone and telegraph systems,particularly in cases where a large number of lines are arrangedtogether in a cable, to prevent or greatly reduce the confusion andother disadvantages due to the long period heretofore required in makingthe tests preliminary to makingv such connections, to enable individualconductors to be identified quickly and with certainty even after thecable has been suspended or placed in operative position under exposureto dampness or atmospheric iniiuences, and to secure other advantagesand results, some of which may be referred to hereinafter in connectionwith the description of the working parts.

The invention consists in the arrangements and combinations of parts ofthe same, all substantially as will be hereinafter set forth, andfinally embraced in the clauses of the claim.

Referring to the accompanying drawings,in which like letters ofreference indicate corresponding parts in each of the several views,Figure l is a side elevation of what is commonly known as a straightsplice. Fig. 2 is an elevation of abranch or tap splice of a cable,tele-graphic or telephonie, the same being broken away to show moreclearly the features of novelty therein. Fig. 3 is an elevation of anindividual wire, showing an insu-l lated sleeve covering the exposedends of the connections or joints in said wire. Fig. i is a section ofthe same, taken at line as; and Fig. 5 shows a modified construction, aswill be hereinafter described.

In said drawings, a 0L indicate collections of electricalconducting-wires, each wire being suitably provided with an insulatingjacket or covering, said wires being united or held together to `formcables. b b are lead tubes inclosing said cables and holding the wiresthereof together'.

c is a splice-tube, also preferably of lead and of a larger diameterthan the tubes b b 6o and being at its opposite ends soldered to thesmaller tubes b b to prevent the introduction of moisture or dampness tothe interior. Within the enlarged tube or splice-tube the ends of themeeting wires are joined and the connections are each covered by aninsulating-sleeve CZ, by means of which the joints are each protectedfrom contact with other similar joints within the splice.

It has been heretofore the practice in con- 7o records, dsc. In makingnew connections with one or more of the wires of a cable distant fromthe office or central point referred to it has been heretofore necessarywhen changing a branch or tap from one main cable or compleurent toanother after removing the lead 8o sleeve and loosening the severalwires from the filling of paraffin commonly employed to test the wiresindividually by means of a suitable instrument, this action of testingcontinuing until the wires to be connected are discovered. Thisoperation of testing is oftentimes extremely tedious and laborious, sothat the connections are made at great expense and with greatdifficulty, and, furthermore,

because of the time occupied in making such 9o tests the interruption tothe systematic working at the office is great and troublesome, forreasons that will be readily understood. By my present invention I avoidall such testing and am enabled to at once select the wires to beconnected. I accomplish these results by putting upon the severalsleeves at the splice identifying-marks, such as the numbers e, andtheseidentifying-marks correspond, preferably, with the numbers upon thewires at roo the central office, and thus t-he workmen after opening thesplice will be enabled to make the selection referred to. I may placethese numbers or identifyingmarks upon the sleeves covering the exposedends o'f lthe individual Wires at the joint thereon, or, as illustratedin Fig. 5, the numbers may be imprinted ou or applied to a specialtube-like sleeve inclosing the wires, as shown. By making theidentifying device in the form of a sleeve I am enabled to thus identifythe Wires without increasing the bulk of the cable or so that the spliceis not as a whole increased in diameter; neither is the operationofloosening the wires preliminary to making a connection interferedwith. The sleeves being marked with identifying-numbers and being placedin position to cover thejoints, the large splice-tube c is placed overthe collection of marked sleeves and is then soldered to the smallertubes b Z), and thus said marks of identification are fully protectedfrom dampness or atmospheric influences, and even should the splice-tubenot be open for years, yet upon a pressing or other occasion when saidtube is opened for purposes of testing the marks Will be preserved andin condition to be clearly and easily recognized and the wiresidentified.

Having thus described the invention, what I claim as new is- 1. 'lliecombination with an electrical cable composed of a multiplicity ofinsulated wires each carrying a local mark of identification, of ahermetically-sealed inclosure for protecting and preserving said marksof identification.

2. The combination with electrical cables inclosed in lead tubes, eachcable consisting of a multiplicity of insulated wires, the Wires of thecables being joined, the Wire of one cable with a corresponding Wire inthe other, the joined wires at each joint carrying a sleeve movablelengthwise to and from the joint and the said sleeves being eachprovided with a local mark of identification, of a splice-tube largerthan the tubes covering said cables and soldered at its opposite ends tothe last said tubes and hermetically inclosing and sealing theidentilied Wires and protecting and preserving the marks ofidentification, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of September, 1900.

JOHN D. PEACHEY.
